How to Properly Use a Hydraulic Breaker?
A hydraulic breaker is one of the most commonly used attachments for excavators, often required for crushing operations in demolition, mining, and urban construction. Proper operation will facilitate the quick progress of crushing work.
Conversely, insufficient operation will result in the inability to fully exert the impact force, and at the same time, the impact force of the breaker will rebound to the breaker body, protective plate, and the operating arm of the machine, causing damage to these parts. This not only delays the construction schedule but also easily damages the breaker itself.
So, how should a hydraulic breaker be properly used?
1. Pre-operation Inspection and Maintenance
Before starting the crushing operation, it is necessary to conduct a pre-operation inspection. Firstly, check whether the high and low-pressure hoses of the breaker are loose, and inspect for any oil leaks elsewhere. Additionally, regularly check the nitrogen pressure inside the breaker.
2. Vertical Striking
Before starting the breaker operation, place the chisel vertically on the material to be crushed, and ensure its stability before starting the breaker. During crushing operations, always ensure that the chisel is perpendicular to the object being struck; if it is inclined to the striking surface, the chisel may slide off, damaging the chisel and piston of the breaker.
3. Avoid Air Strikes
Avoid allowing the breaker to strike without a target. When the rock or target object has been crushed, immediately stop the striking action of the breaker. Continuous aimless impacts will only cause loosening and damage to the front body and main body screws, or even damage to the machinery. Aimless striking conditions, except for improper insertion, can also be caused by shaking the breaker during use.
4. Do Not Push Heavy Objects or Large Rocks with the Breaker
Do not use the protective plate as a tool for pushing heavy objects, as this will only cause damage to the protective plate screws, chisel rod fracture, and damage to the breaker, and may even be the main cause of the boom's fracture.
5. Avoid Shaking the Chisel Rod
During crushing operations, attempting to shake the chisel rod may result in possible fractures of both the main body screws and the chisel rod.
6. Do Not Operate in Water
The hydraulic breaker is not a sealed structure and should not be immersed in water as it can damage the piston cylinder and contaminate the excavator's hydraulic system. Therefore, try to avoid working in rainy conditions or in water. Except for the chisel, other parts should not be submerged in water.
7. Avoid Prolonged Striking
If the target object has not been crushed after continuously striking the same point for more than one minute, change the striking point and try again. Continuously striking the same point will only cause excessive wear of the chisel rod.
8. Do Not Operate When the Hydraulic Cylinders are Fully Extended or Retracted
Operating the breaker when the hydraulic cylinders of the excavator are fully extended or retracted will cause the impact vibration to reverberate back to the hydraulic cylinders, resulting in severe damage to the excavator.
